for use on the suction and discharge sides of pumping devices in order to relieve the pipe line of vibration; the coupling is also adapted for'use as a flexible connection in any hydraulic line, pumping water or water and other substances.

The principal object of my invention is to provide a new and improved device of the class described wherein the parts of the coupling by which the flexibility thereof is provided are protected in a greater degree from injury or from contact with the materials passing through the coupling, thereby prolonging the life of the parts and enabling the device to be used with greater eiiiciency.

Other objects and advantages of the invention will appear as the description thereof proceeds, all of which is particularly pointed out and included in the appended claim.

Reference is to be had to the accompanying drawings forming a part of this speci- 'whereby bolts may fication, in which similar characters of reference denote corresponding parts in'all the views, and in which Figure .1 is a vertical sectional view of the coupling; Fig. 2 is an end view thereof.

The coupling is designed to be attached to the adjacent ends of any suitable pipes or connections carried by cylinders or other devices, the size of the parts and the material of which they are made depending on the particular use to which the construction is adapted, variations in such matters being comprehended within the appended claim.

The coupling comprises a plurality of nipples l, 2, each being provided atone end with a peripheral. flange 3, each flange being provided with suitable openings 4.- be used to secure the nipples in "position.

The opposite end of the nipple 2 is provided with a peripheral flange 5 having openings passing therethrough; the inter- Specification 52 Letters Batent; Application ,fllefl may, 15, 1912., Serial No. 697,375.

placed on the outside of each of the washers, the bolts 9 passing through the rings as well as the washers. 4

The engagement between the flange 5 and the inner peripheral edge portion of the washer 7 is rendered more efficient by means of a ring 1.3 bearing against the washer, the inner peripheral edge of the washer 8 beand the flange 5 ing also held in better and more secure position against the shoulder 6 by means of the ring 14 through which the bolts 10 pass.

Referring particularly to Fig. 1 it is to be noted that the shoulder 6 on the nipple 1 is not adjacent the end portion of the nipple; by providing this shoulder intermediate the ends of the nipple I provide a structure wherein the adjacent or meeting ends of the nipples may be more securelyheld together, and to this end it may bedesirable to have the side walls of the nipples tapering, as shown particularly to Fig. 1, whereby movement of one relatively to the other permits the one end portion to be positioned closely adjacent or within the other end portion.

it is also clear that the use ol'- the coupling herein described and claimed prevents contact of the liquid passing therethrough with the flexible elements 7 8, thereby prolonging the life of the same and protecting them in a greater degree from Having thus described my invention, I

re to secure by Letters A pipe coupling comprising a nipple havange at one end thereof, the opening 5. extending through the nipple being tapering, a thereon lntermediate second nipple. having a shoulder its ends, the second nipple beyond the shoulder being adapted to enter into the said larger open end of the 10 first nipple, a flexible flange of the first ni element secured to the pple, another flexible element secured to the shoulder of the second nipple, together with rings engaging the peripheral portionsof the said flexible elements, whereby they are held together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
